It's sometimes useful to have a batch of tests to be run in a variety of
different scenarios. In particular it's sometimes useful to reuse those
tests for scenarios that aren't known at the time of writing the tests.
Introduce the 'test_output' decorator. This creates a number of tests by
feeding the output of the decorated function (representing the scenario
setup) into all of the listed tests.
